Language constructing language: the implications of reflexivity for linguistic theory

What if there were no reflexive language? If no language had any

reflexive properties? Or to put it another way: What if we did not

have and had never developed any metalinguistic vocabulary or

metadiscursive techniques for talking about our language and its

everyday uses – the language that is sometimes called, our ‘primary’

or ‘object’ language? What would be the consequences?
